Preoperative and follow-up lumbar MRIs of the patient using bone-anchor suture technique. (A) Indicates the preoperative sagittal and axial MRIs, showing L4/5 herniation with spinal cord compression. (B) To avoid the artifact signal of spinal cord edema in immediate postoperative MRI examination, MRI re-examined at three-month follow-up indicates the spinal cord and nerve root were decompressed. (C) indicates the lumbar MRIs at one-year follow-up.
